FIELD

The present invention is generally related to a device and method fordisinfecting a medical instrument with ozone, in particular theinvention relates to a device and method for disinfecting a continuouspositive airway pressure (CPAP) device.

BACKGROUND

Sleep apnea is a common sleep disorder characterized by abnormalbreathing during sleep. Pauses in breathing for people with sleep apneacan last from a few seconds to minutes during sleep, often resulting insignificant levels of sleep disturbance, which may result in daytimefatigue, impaired reaction time, vision problems, and impaired daytimecognition.

Sleep apnea is often treated with a continuous positive airway pressure(CPAP) device. CPAP devices prevent reduction of oxygen levels in theblood and sleep loss by delivering a stream of pressured air through ahose to a nasal pillow or full facemask surrounding a patient's nose.The CPAP devices work by blowing air at a prescribed pressure for eachpatient, and keeping the air passage open to maintain unobstructedbreathing throughout a sleep period.

While CPAP treatment can be a highly effective treatment for sleepapnea, a major downside with CPAP treatment is non-compliance by users.Users are often reluctant to continuously use CPAP devices because thenose and face masks may be uncomfortable. In addition, maintenance ofmany CPAP devices has proved to be tiring and difficult for users, aswater vapor running through the hoses and masks of a device may causebacterial build-up and require continuous cleaning and prevention asnecessary steps to safely use a device, which may result in furthernon-compliance by users. Most manufacturers of CPAP devices recommendthat users perform daily and weekly maintenance on their machines toprevent bacteria and mold buildup. In this instance, each part of theCPAP device needs to be cleaned individually, including the mask, thehoses and the humidification portion, which is difficult and timeconsuming for users on a daily or weekly basis. Other CPAP devicecleaning methods include soaking the component parts of a CPAP device ina mixture of vinegar and water to disinfect the component parts. Becauseof the inherent nature for CPAP devices to collect bacteria and mold, anumber of other products are available to consumers to make CPAPmachines safer, including but not limited to: Citrus II Cleaning Sprayfor masks and tubing, available at www.cpapxchange.com

DETAILED DESCRIPTION

FIG. 1 shows a perspective view of an ozone device 100 connected to aCPAP device 105. In this embodiment an ozone compartment 110 for housingan ozone operating system 115 is shown in the ozone device 100. Inaccordance with this embodiment, the ozone operating system 115 producesand transfers ozone to the CPAP device 105 to disinfect the CPAP device105 before or after use by a user.

In accordance with this embodiment, the ozone operating system 115 pullsin ambient air into an air pump to create ozone. The air pump maytransfer the ambient air to a corona discharge ozone generator, whichmay create about 400 mg/hr of ozone gas, which may be used to disinfecta CPAP device 105. In accordance with this embodiment, the ozone may bepumped directly into the CPAP device 105 and/or a water reservoir tank122 from the ozone compartment 110 through an ozone distribution line118 that connects to the CPAP connector unit 130, for providing ozone todisinfect the CPAP device 105. In accordance with the device shown inFIG. 1 the ozone may enter the ozone distribution line 118 when poweredby a small air pump, such as an aquarium pump, and then migrate throughthe distribution line 118, through a CPAP connector unit 130, and intothe water reservoir 122. The ozone distribution line 118 traverses intothe hose 124 and the CPAP connector unit 130 and ends with a free endimmersed in the CPAP water reservoir 122. The ozone may then be releasedinto water in the water reservoir 122, acting to disinfect and sanitizethe water reservoir 122, and may then release as free ozone from thewater in the water reservoir 122. The free ozone may then traverse intothe hose 124, which then carries the ozone into a mask compartment 116to sanitize a mask 112. Within about 20-30 minutes from the start of theozone sanitizing process described, the ozone will naturally breakdowninto oxygen O², resulting in a CPAP device 100 with an automateddisinfecting process with ozone passing through and disinfecting theCPAP water reservoir 122, the water in the reservoir, the hose 124, themask compartment 116 and the mask 112. As an additional safetyprecaution to make sure all ozone is released from the CPAP device 105before a user utilizes the CPAP device 105, an oxidizing catalyst, suchas an MgO filter, may be on the ozone device 100, such as on the backside of the mask compartment 116 to collect, breakdown and releaseremaining ozone as oxygen O².

The ozone compartment 110, in accordance with the present embodiment ofthe present invention may be any available ozonator or a like device forcreating ozone gas. Ozonators create ozone from oxygen molecules, oftenby applying ultraviolet light to the oxygen. Ozone gas is made of oxygenmolecules that have been ionized by radiation to form groups of threeoxygen atoms, O³. The ozone gas is powerful and effective for removal ofodors, impurities and dangerous pathogens, working by exchangingelectron charge with particles that ozone comes into contact with toform oxygen, O², from the unstable ozone O³, a process particularlyuseful for purifying air and water and for killing bacteria andmicroorganisms. Typically, ozone, O³, will convert back to oxygen, O²,within two hours of the start of a cycle.

In accordance with the embodiment shown in FIG. 1, a small air pump isprovided in the ozone compartment 110 to push ozone into the waterreservoir 122. An exhaust port is further provided in the maskcompartment 116 and has two main functions; the first is to draw thefree ozone up into the hose 124 from the water reservoir 122 and intothe mask 112 from the water reservoir 122. The free ozone will work todisinfect the water reservoir 122, the hose 124, and the mask 112. Afterexiting the mask 112 the free ozone then will be drawn out of the maskcompartment 116 through the exhaust port into the free atmosphere asoxygen O². Further shown in this embodiment is a user interface 111 fora user to set a sanitizing schedule on the ozone device 100 and a topcover 113 to close the ozone device 100.

FIG. 2 is a side view of a CPAP connector unit 230 attaching the ozonedistribution line 218 from an ozone device to the water reservoir 222 ofa CPAP device in accordance with another embodiment of the presentinvention. In accordance with this embodiment the ozone distributionline 218 is shown connected through the CPAP connector unit 230, at aninety degree angle, and into the water reservoir 222. The ozone may bedistributed from the ozone distribution line 218 into the water 219. Theozone 221 may effectively sanitize the water and kill bacteria andmicroorganisms in the water 219 by oxidizing organics in the water 219.Free ozone 221 that is left after removing organics from the water 219in the water reservoir 222 may then release from the water and pass intothe hose 224 to sanitize the hose and then enter a mask compartment forsanitizing a mask. By sanitizing the ozone water reservoir 222, thewater 219, the hose 224 and the mask after each use, a user mayeffectively clean and sanitize their CPAP machines on a daily basis anduse the machine with a decreased risk of discomfort, infection orbacteria growth in their CPAP device. While the CPAP device may stillneed to be cleaned in accordance with a manufacturer's requirements, thepresent invention will assist a user to maintain a safe to use device ona regular basis and improve compliance and use of the CPAP device totreat sleep apnea. The inventors expect that the current invention willassist people with sleep apnea to easily disinfect their CPAP device anduse their machines safely in accordance with personal preferences androutine schedules.
